EOSDIS Data News: October 6, 2017

NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published beta versions of the Lightning Imaging Sensor on the International Space Station - LIS (ISS), non-quality-controlled standard products on September 17. These data are made available to users until a manual quality control process is complete, at which time they will be replaced by the archive version of the products.

These data are collected by the LIS (ISS) used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. These data can be used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day and night with high detection efficiency. The data are available in both Hierarchical Data Format (HDF)-4 and netCDF-4 formats. Data is available from 3/1/2017 forward.

NASA's Land Processes DAAC (LP DAAC) publicly released a new collection of Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6 Land Surface Temperature and Emissivity (LST&E) data products on September 21. These products (M*D21's) offer an alternative to the previously released M*D11 LST&E data collection as they differ in algorithm composition and implementation. M*D21 datasets are available at 1 kilometer resolution for 5-minute, daily, and eight-day temporal periods. There is a total of eight products in the collection.

NSIDC DAAC published new data to the NASA IceBridge DMS L1B Geolocated and Orthorectified Images dataset for the Summer 2017 Arctic campaign. This dataset contains Level-1B imagery taken from the DMS over Greenland and Antarctica.

NSIDC DAAC has published data from the Special Sensor Microwave Imager/Sounder (SSMIS) F15 sensor to Making Earth System data records for Use in Research Environments (MEaSUREs) Calibrated Enhanced-Resolution Passive Microwave Daily Equal-Area Scalable Earth (EASE)-Grid 2.0 Brightness Temperature Earth Science Data Record (ESDR) dataset as version 1.2. The minor change in this version corrects the handling of QC flags to retain more data, eliminating only the flagged data in a given channel and taking care not to eliminate data in other channels. This dataset is part of the MEaSUREs Program.

NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Carbon Arctic Reservoir Vulnerability Experiment (CARVE) dataset Daily Thaw State of Boreal and Arctic Alaska from the Advanced Microwave Scanning Radiometer (AMSR-E) and the Special Sensor Microwave Imager (SSM/I), 2003-2014. This dataset provides daily 10 km resolution maps of the Alaskan and Arctic Boreal land surface state as either frozen, melting, or thawed. These data are generated from passive microwave radiometer observations made from 2003 through 2014.

ORNL DAAC published the dataset CARVE: In-flight Videos from the CARVE Aircraft, Alaska, 2012-2015. This dataset contains videos captured by a camera mounted on the CARVE aircraft during airborne campaigns over the Alaskan and Canadian Arctic. Flight campaigns took place from 2012 to 2015 between the months of March and November to enable investigation of both seasonal and inter-annual variability in atmospheric gas content.

ORNL DAAC published the CARVE: Daily Flight Reports, 2012-2015. This dataset includes detailed daily flight reports from each of the airborne campaigns over the Alaskan and Canadian Arctic for CARVE. The reports include plots of the flight path, altitude, wind and weather conditions, IR and visible light images, and initial analysis of the atmospheric gas concentrations encountered along the flight. Flight campaigns took place from 2012 to 2015 between the months of March and November to enable investigation of both seasonal and inter-annual variability in atmospheric gas content.

ORNL DAAC published the CARVE In-flight Photos from the CARVE Aircraft, Alaska, 2013-2015. This dataset contains photos taken by scientists aboard the CARVE aircraft during airborne campaigns over the Alaskan and Canadian Arctic. Flight campaigns took place from 2012 to 2015 between the months of March and November to enable investigation of both seasonal and inter-annual variability in atmospheric gas content.

ORNL DAAC published the ABoVE dataset Cumulative Annual Burned Area, Circumpolar High Northern Latitudes, 2001-2015. This dataset provides annual cumulative end-of-season burned area in circumpolar high northern latitudes (HNL) above 60 degrees for the years 2001-2015. The data were generated using the Arctic Boreal Burned Area (ABBA) product (a MODIS-based algorithm). The product is delivered in two spatial domains: circumpolar and a North American subset for areas above 60 degree north.

ORNL DAAC published a revised the Boreal Ecosystem-Atmosphere Study (BOREAS) dataset BOREAS TE-13 Biometry Reports. BOREAS Terrestrial Ecology (TE)-13 team collected data on site characteristics, soil profiles, woody debris, overstory vegetation, and understory vegetation from approximately 100 sites in the Southern Study Area (SSA), Northern Study Area (NSA), and Transect Areas in the boreal forest. This dataset provides 3 reports published by the Canadian Forest Service for the BOREAS project in pdf file format.
